Narraway joined Gloucester in 2002 and went on to make 163 appearances for the Cherry and Whites before signing for Perpignan.

During his time in the West Country he won the European Challenge Cup and LV=Cup.

Narraway has been capped seven times by England and has represented the national side at every level from the under-18s to the senior team. He was a member of the England U21 side that won a first Six Nations Grand Slam in 2004.

London Irish director of rugby Brian Smith said: “Luke is a talented player with a huge amount of Premiership experience. As a club, we want to be challenging for silverware and we need the right type of player to achieve those goals. I had the pleasure of working with Luke in the England set up and look forward to doing so again next season. He has bought into what we want to accomplish and therefore is a perfect fit for London Irish.”

Narraway said: “There has been a lot of positive news to come out of London Irish over the last six months, not least with the announcement of the new Board of Directors and the move to a new state of the art training ground. I’m excited with the direction the club are heading and I’m looking forward to being a part of their plans.”
